Patent

CA 2647388

In a switching device, such as a residual current circuit breaker or a combination switch, for example, for interrupting and switching at least one line (L1, L2, L3, N), having a tripping device (2) which is independent of the system voltage, having a tripping element (3) associated with said tripping device, such as a tripping relay, for example, and having a tripping device (9) which is dependent on the system voltage, the invention proposes, for simplifying the design, for reducing the required assemblies, for easy adaptability and for an increased functional reliability, that the tripping device (9) which is dependent on the system voltage comprises means for tripping the tripping element (3), which is associated with the tripping device (2) which is independent of the system voltage.

L'invention concerne un dispositif de commutation comme, par exemple, un disjoncteur différentiel ou un commutateur combiné pour interrompre et commuter au moins une ligne (L1, L2, L3, N), comprenant un dispositif (2) de déclenchement indépendant de la tension du réseau, comprenant un élément (3) de déclenchement associé à celui-ci comme, par exemple, un relais de déclenchement, et comprenant un dispositif (9) de déclenchement dépendant de la tension du réseau, et il est prévu, pour simplifier la constitution, pour réduire les sous-ensembles nécessaires, pour faciliter l'adaptation et pour accroître la fiabilité de fonctionnement, que le dispositif (9) de déclenchement dépendant de la tension du réseau comprenne des moyens pour déclencher l'élément (3) de déclenchement associé au dispositif (2) de déclenchement indépendant de la tension du réseau.
